STREET-TRAFFIC-DIRECTION-SIGNALING DEVICE.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed March 27, 1920. Serial No. 369,218.

To all whom it may concern.

Be it known thatI, Josnrn W. BRENKERT, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Street-Trafiic-Direction signaling Devices, of which the follow ing is a specification.

My invention relates. to a street crossing traffic signaling mechanism for indicating the direction the traffic will. take at street crossings in congested districts in cities and the objects of my invention are: first, to pro vide a traffic signaling device to be operated by a traffic officer for indicating the direction of traflie at crossings; second, to provide a device of this class which is actuated by the foot of the operator for revolving an indicating arm for indicating the direction of trafiic; third, to provide a device of this class whichis easily operated and will maintain it position until reversed by the operator; fourth, to provide-a. device of this class which is light and portable and may be readily carried to the place: of operation by the operator and fifth, to provide a device of this class which is very simple and economical of construction, durable, easy to operate and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a side elevational view of my device; Fig. 2 is a side elevational view at a right angle thereto showing a portion broken away and in section to facilitate the illustration; Fig. 3 is a sectional View through 3-3 of Fig. 1 and Fig. 4 is a sec tional view through 44 of Fig. 1 on an enlarged scale.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The base member 1, upright 2, support 3, levers 4 and 5, operating arm 6, revoluble member 7, staff 8 and signal members 9 constitute the principal parts and portions of my street traffic gna ng e ce.- The base member 1 is provided with a lower fiat surface for positioning on the street and is of sufficient size and weight to support the device in position. It is provided centrally with an upright member 2 extending upwardly some distance and on the front side is provided with a reinforced boss 2 and. revolubly mounted therein is shaft 2 which is provided with a partial. ball member 2. Pivotally mounted on this ball member 2 is the operating arm 6 which extends upwardly some distance and is provided on its upper end with a weight 6 Pivotally mounted on the shaft 2 are the levers 4 and 5 which are bell crank members provided with offset portions adapted to engage the arm 6 and with offset members et and 5" adapted for engagement by the foot of the operator for operating said. levers.

It will be here noted that these levers 4; and 5 are so constructed and positioned that their upright portions are engaged by the arm 6 only when the arm 6 has passed its perpendicular position in moving the lllililiC signal and that the weight 6 functions for shifting the signal after it passes this perpendicular position and it is raised to this perpendicular position by the operator by pressure on the foot levers 4 or 5. Mounted on the base 1, back of the upright 2, is a support 3 which is provided with a right angled turn at its upper end and with a vertical bearing in the upper end forming a journal for the member 7 which is revolubly mounted therein. This member 7 is provided with a ball race 7 in its lower side filled with balls thus providing a ball bearing between the member 7 and the upright member 2. Thi member 7 is provided with a side projecting slotted portion 7 shaped as shown best in Fig. 3 of the drawings and through which the upper end of the arm member 6 extends so that when the arm member 6 is moved in either direction past its upright position it engages the ends of the slots 7 and turns the member 7 on the upright portion 2. This member 7 is also provided with outwardly projecting lugs 7 which are adapted to engage the support 3 when revolved a certain distance thus forming a stop for the revolution of the member 7 at certain predetermined positions. The upper end of the member 7 is provided with a socket with a key way in one side thereof and in which is mounted the staff 8 which is provided with a key adapted to engage said key way for preventing the turning of the staff 8 relatively to the member 7. This staff 8 extends upwardly a suitable distance and on its upper end .is provided a signal member 9 which may be any form desired. It is preferred, however, to have four extended portions which may have characters printed thereon for indicating I whether the trafiic shall proceed or stop.

Though I have shown and described a particular construction, combination and arrangement of parts and portions I do not wish to be limited to this particular conweight 6 revolves the member 7, stafi' 8 and signals'9 to the proper position andis stopped by the lugs 7 engaging the member 3.

Having thus described my invention'what I I claim as new and desire-to secure by Letv ters Patent is:

1. A street crossing traffic direction signal, including a base member, astaif revolubly mounted thereon, provided with a later ally extending side portion, an over center weighted arm pivotally mounted 'on said base member adapted to engage said side portion, operated by the trafiic o flicer for revolving said stafliwmeans for stopping its revolution at a certain pre-determined point and a trailic signal member secured on the upper end of said staff.

2. A street crossing traflic direction signal, including a base member, a stafl revolubly mounted thereon, provided with a laterally extending side portion, a weighted arm pivotally mounted on said base member extending upwardly adapted to swing on its pivotal mounting for engaging said side portion when swung in opposite direction on its pivotal mounting, foot operated means for swinging saidweighted arm on its pivotal mounting, means for stopping its revolution at a certain pre-determined point, and a'traflic signal member secured on the upper end of said-staff. I

3. A device of the class described, include inga basemember provided'with a central upright portion, an arm pivotally mounted thereon extended upwardly, ,a pair of foot levers engaging the opposite side of said arm for shifting the same, another arm secured to said base extending upwardly forming a journal member, a member revolubly mounted in, said journal member and revolubly supported on said central upright support and provided with an extended slotted mem-' ber through which the upper end of said arm passes, a staff securedin the upper end of said revoluble member provided with means for preventing itsvturning in said revoluble member and a trafiic signal secured on the upper end of said stafl. In testimony whereof I have hereunto set my hand atSan Diego, California, this 19th day of March, 1920. 1 V
